Gearank High Notes

JBL won a recommendation from us with the 2nd iteration of the 305, carrying over its best features while mixing in improvements that include improved transient response and linearity, new boundary EQ controls to reduce environment-induced low-frequency anomalies, and improved enclosure material (15mm MDF).

At its core is JBL's 5" woofer and 1" tweeter, with JBL's proprietary Image Control waveguide that allows for easier sweet spot positioning.

  • Amplifier: 41W LF, 41W HF
  • Inputs: 1 x XLR, 1 x 1/4" TRS
  • Frequency response: 49Hz - 20kHz (±3dB), 43Hz - 24kHz (-10dB)
  • Crossover Frequency: 1725Hz
  • Enclosure: Ported
  • Controls: Input Sensitivity, Boundary EQ, HF Trim, Volume
  • Dimensions: 11.75" x 7.3" x 9.1"
  • Weight: 10.43 lbs.

JBL 305P MKII Frequency Response Chart


The JBL 305P MKII's strong point is its sound quality, which many consider as incredible when considering its price point. Many users specifically mention its highs and midrange to be very life-like, and they report that it helped them hear nuances that they were not able to with their old monitors. The speaker's build quality also gets a lot of thumbs up.


Some users complain that the low-end is lacking, but given its small 5" woofer, this is to be expected. There are also a few who note that it distorts when pushed hard, but this is more of a physical limitation than a problem.


If you're looking for a great value studio monitor that performs well even in untreated rooms, the 305p MKII is a good choice. Low end may be lacking but in rooms with less than stellar acoustics, a conservative low-frequency output prevents unrealistic low-frequency projection.

Although this was previously on our recommended list, there are now more highly rated options available which you can see in our guide to The Best Studio Monitors.
